Is open-cell spray foam the right insulation for your Wildomar home?
Open-cell foam insulation is a soft spray foam we install in Wildomar attics, rooflines and walls to slow heat, close air gaps and quiet the house. A trained applicator sprays it from a professional two-part, high-pressure rig.
Most people call us because a room upstairs won't cool down, the power bill keeps climbing, or they can hear every footstep through the ceiling. The price moves with the area we're spraying, how thick the foam goes, and whether old insulation has to come out first through insulation removal. The schedule turns on the same kind of thing, like a roof leak or a wiring repair that has to be fixed before any foam goes on, plus finding a day when your household can be out of the house. I'll give you your own number once I've seen the space.
How do you know your house could use open-cell foam?
Upstairs rooms stay hot
The bedrooms upstairs run warmer than the rest of the house all afternoon, even with the AC turned down. That usually means thin or settled attic insulation and air leaking through gaps, and every summer you wait, the AC works harder and the power bill shows it.
You hear every room
The TV, footsteps and the washer carry through walls and floors like they aren't there. Empty wall and floor cavities pass sound easily, and if a remodel is coming, that's the cheapest time to fill them, before the drywall closes up again.
Dust lines and drafts
Gray dust streaks show at the carpet edges, and you feel air moving at the attic hatch or around the can lights. Those are air leaks, and insulation laid over them keeps fighting the draft, so the longer they stay open, the more cooled air you pay to lose.
How we install open-cell foam insulation
I start by getting into the attic, walls or crawl space and telling you what's actually up there, because foam sprayed over a roof leak, a bad wire or old insulation full of droppings just hides the problem. Anything like that gets fixed or pulled out first. Then we seal the gaps around pipes, lights and the hatch, cover what needs protecting, and spray, keeping the foam as deep at the edges as it is in the middle. Open cell costs less and quiets a room better, so it suits you if sound matters more to you than squeezing out every bit of insulating power. When we spray under the roof deck to close off the whole attic, which the trade calls an unvented attic, we plan how moisture gets out of that space as part of the job, because a sealed attic still needs a way to get rid of it. If your ducts aren't up there, I'll usually tell you that sealing the gaps and topping up with blown-in insulation, which is loose fill blown through a hose, is the better buy.
Open cell lets moisture pass through it, so it can't stop damp coming up from the ground. Under a house with a wet crawl space, we put down a crawl space vapor barrier instead of counting on foam. We also spray open cell in offices and shops to cut noise between rooms as part of our commercial insulation work.
Under the roof deck
This suits houses with ducts in the attic, because spraying the roofline brings the ducts inside the cooled part of the house instead of leaving them in the heat. It's the bigger job, and it's the one where the moisture plan matters most.
Walls and floors between rooms
This suits bedrooms, home offices and media rooms where noise is the complaint, because the soft foam fills every corner of the cavity, and corners are where sound gets through. It's easiest while walls are open.
The room over the garage
This suits the bonus room that's hot in summer and chilly in winter, because foam in its floor and outside walls closes the leaks to the garage below while it insulates. Most of these rooms were built with very little up there.

What happens after you call about open-cell foam in Wildomar
Here's how a foam job runs from your side, from the first call to the walk-through at the end.
Call or send the form
Tell us which space you want foamed and roughly how big it is. We'll set up a time for me to come out and look.
I look before I quote
I go into the space myself, and before I leave I tell you what I'd do, what has to be fixed first and what I'd skip. Your price comes from what I actually saw, not from a guess over the phone.
We set the spray day
Once you say go, we take care of the permit step if there is one and pick a day. Wildomar allows construction Monday through Saturday from 6:30 a.m. to 7:00 p.m., and none on Sundays or city holidays, so we book the spraying and cleanup inside those hours.
Seal, spray, then walk it
We seal before we insulate, spray the foam, and then walk the finished space with you so you can see the coverage at the edges as well as the middle. Your household stays out for the spray and for a while after it, which the questions below cover.
Why Wildomar homeowners call Premium Wildomar Spray Foam Insulation for open-cell foam
I look at every job myself
I come out to see the attic, walls or crawl space and plan the job, and I work alongside the small crew that does the install. You hear what's up there from someone who'll be up there with the crew.
Started in Wildomar in 2013
I grew up following my dad through attics on his insulation jobs, and I started this business here in 2013. We're based in Wildomar, so the houses and attics around here are what we work in.
Licensed and insured in California
We're licensed and insured. The state licensing board counts installing any insulation for heat or sound control as insulation and acoustical work, so foam put in for quieter rooms falls under the same licensing as any other insulation job.
Satisfaction guaranteed on every job
Satisfaction guaranteed on every job, and we back it by doing repairs and old-insulation removal before any foam goes on. Foam sprayed over a leak or a bad wire only hides the problem.
On a foam job, what's under the foam matters most, so the first step is getting me into your attic. Ask for a visit or call (951) 417-1017.
Spray foam, permits and attic work in Wildomar
Wildomar's Building and Safety Department issues the city's construction permits, including building, electrical, plumbing and mechanical permits. I won't guess whether your foam job needs one, because that can turn on what else the work touches. We check with the building office for your address, whether that's the city or the county, and when a permit is needed we file it and keep you posted.
We're based in Wildomar and work in the cities around it, and a lot of the homes we see have ductwork running through a hot attic, which is where spraying the roofline earns its cost. Older houses tend to have thin, dusty insulation that's been walked flat, and we find the same mix on jobs in Murrieta and Lake Elsinore.
Questions about open-cell foam in Wildomar
How much does open-cell spray foam insulation cost in Wildomar?
Open-cell spray foam in the Riverside area usually costs about $0.60 to $1 per board foot, a unit that counts both the area covered and how thick the foam goes. That's the going rate in the area, not our quote. Your total depends on how much space we're spraying, the depth it needs and any prep work, and you get your own number after my visit.
How long do we have to stay out of the house after spray foam insulation?
Plan on everyone being out of the house for at least 24 hours. When it's safe to come back depends on the product, the kind of house and whether children or older family members live there, so line up a place to stay before spray day. We'll go over the timing for your house when we set the date.
Is open-cell or closed-cell foam better for my home?
Closed-cell is better if you need the most insulating power from a thin layer, and open-cell is better if you want quieter rooms for less money. Closed-cell, a dense foam that also blocks moisture, is about twice as energy efficient per inch and costs more. Open-cell is a much better sound barrier.
Does open-cell spray foam need to be covered after it's installed?
Yes, when the product's instructions or the building code call for it. In that case a fire-protective covering, such as a coating or drywall, goes over the foam. We check which applies to your space and plan it into the job, so it's in the price from the start.
How do I handle repairs near spray foam insulation later on?
Tell any plumber or electrician working near the foam not to heat it or grind it, because heated or ground spray foam can give off toxic fumes. If someone needs to get into a foamed wall or roofline, call us and we'll talk through where the foam sits.
Does California's energy code apply to insulation upgrades in older homes?
Yes. California's Energy Code covers alterations to existing homes, not only new construction and additions. It sets energy and indoor air quality requirements, so it's part of what we check when we plan an insulation upgrade on an older Wildomar house.
